What type of cancer?
Optional but helpful: We'll highlight the most relevant research for your cancer type on the Research tab, and surface any known compound synergies on your dose page.
Your approximate body weight?
Why we ask: These protocols are dosed by body weight, just like many prescription medications. Ivermectin, for example, is calculated at a specific milligram amount per kilogram of body weight. Getting this right helps ensure you're seeing accurate numbers for your situation — not a generic estimate.

What form of ivermectin do you have?
Why this matters: Ivermectin comes in very different concentrations depending on the product. A 1.87% OTC paste syringe, a liquid cattle drench, and a compounded pharmacy tablet all contain the same active ingredient — but at wildly different strengths. Getting the math wrong here means your actual dose could be 10× too high or too low. Select what you have (or plan to get) and we'll show you exactly how much to use.

🐾 Pet Protocol
What kind of pet?
🐕 Dog Breed
What breed?
This matters. Several breeds carry the MDR1/ABCB1 gene mutation that makes ivermectin potentially fatal at doses that are safe for other dogs.
⚠ = MDR1 mutation risk. These breeds will receive a fenbendazole-only protocol.
🛑 Ivermectin is not safe for this breed
Collies, Australian Shepherds, Shelties, Border Collies, and related herding breeds frequently carry the MDR1 (ABCB1) gene mutation. This mutation prevents the blood-brain barrier from pumping ivermectin out of the brain, causing ivermectin to accumulate to toxic and potentially fatal levels — even at doses that are completely safe in other dogs.
We have automatically excluded ivermectin from your pet's protocol. Your pet can still benefit from fenbendazole (FBZ), which does not carry this risk.

Track your progress — enter the date you started (or plan to start) your protocol.
✅ Fatigue, brain fog, mild headache
Likely die-off (Herx reaction). Increase your binder dose — take it 2–3 hours after each compound dose, never before. Drink more water. Rest. These symptoms usually peak around days 2–5 and fade as your body clears the debris. Do not stop your protocol.
✅ Nausea, loose stools, mild joint aches
Likely die-off or absorption issue. Take ivermectin and fenbendazole with a larger fatty meal. Try splitting your fenbendazole dose across two meals. Add a binder dose at bedtime. Continue protocol.
⚠️ Persistent nausea, loss of appetite, upper right abdominal pain
Possible liver strain. Pause your protocol immediately. Continue taking binders during the pause to help clear circulating toxins. Get liver function tests (AST/ALT) immediately. Resume only when levels normalize — and when you do, take binders 2–3 hours after each dose, never before. Consider dropping one dose tier.
🛑 Yellowing skin or eyes (jaundice), severe abdominal pain, shortness of breath, vision changes, severe rash
Stop the protocol immediately and seek emergency care. These are not Herxheimer symptoms. Call 911 or go to an emergency room.

Ivermectin, fenbendazole, and mebendazole all process through the liver. Get a baseline before you start anything above the Low tier so you know what's normal for you, and re-test on the cadence below. The published Baghli/Marik/Makis 2024 protocol calls for weekly liver function tests at the High and Advanced tiers. Case reports describe drug-induced liver injury when fenbendazole is combined with checkpoint inhibitor immunotherapy (Keytruda/pembrolizumab, Opdivo/nivolumab) — if you're on either, talk to your oncologist before starting.
What to test
AST, ALT, GGT, and total bilirubin (TBILI) are the four core liver markers. The kit below also includes HbA1c (blood glucose), HsCRP (inflammation), and a full metabolic snapshot — useful baseline data even outside this protocol.
When to test
Once before starting (any tier above Low) · every 1–2 weeks during High or Advanced tiers · once at protocol end.

⚠ What is a Herxheimer reaction?
When antiparasitics kill parasites and cancer cells, the dying cells release a flood of toxins — heavy metals, bacterial waste, mold byproducts, and cell debris — faster than your liver and kidneys can clean them out. This toxic overload washes back into your bloodstream. The result — known as a “Herx reaction” or die-off — is sudden fatigue, brain fog, headaches, nausea, joint pain, and flu-like symptoms. Many people think this is a bad reaction to the medication and stop the protocol. It's not. The medication is working — but the waste has nowhere to go. Binders give it an exit route.
Dose & Timing
📏 Start at 1 g activated charcoal per dose, 1–2× daily. Work your way up to 2–3 g per dose only if die-off symptoms (fatigue, headache, nausea) are strong. Stop increasing if you get constipated — that's your body's limit.
⏱ Take binders 2–3 hours after each ivermectin, fenbendazole, or mebendazole dose — never before.
📅 Start binders 3–5 days before beginning the protocol to prepare your body's detox system.
Activated charcoal binds anything it touches in your gut — it can't tell the difference between die-off toxins and your medication. If taken before a compound dose, it traps the medication and stops it from being absorbed. The same rule applies to any other pill you take by mouth (thyroid, birth control, antidepressants, etc.) — space them by at least 2 hours. Taking charcoal every day for a long time can also soak up vitamins (A, D, E, K) and minerals, so talk to a doctor if you plan to use it for more than a few weeks.
